There is the cost for four of them, you might need to mod the fenders, you might be pushing your wheels out an inch or more. You might also will change the way the car handles with that much extra offset, that will need to be corrected.

actually, i chose the thinnest thickness.... 19mm (0.75in)
i dont think i need to roll the fenders... especially since the rims are only 17"

Do you have the rims yet? I ask because not all 17" fit our cars. Most do, but some might not clear the brakes ( if you have a base A/T that came with 16's this is not a concern). I wouldn't commit to four adapters till you did a test fit. Can you get one and do a test fit?
